Text nodes could automatically render basic html, specifically <a href=... but also <b> <i> and <u>

At this moment text nodes can't render html and specifically hyperlinks.

This ability to open a basic link from a text node would be very useful, especially when one is trying to compete with Adobe AIR

At this stage, I'm not aware of a way of doing this without breaking things into multiple text nodes where the hyperlink is a text node on its own with an onMouseOver event that does the underline/open link bit.
